Clairsville, in lthe county of Belmont and Improvements in `AntiskidDevice s f or Ve-f'" hicleV Wheels, of'which the following 1s a 'Mypreset invention has reiferenc'eto-'air anti-skid device for vehicle wheels.

M lob'ectl isf to reduce a rdevicejof this y' 'J p ner vface of one oftheshoes.

. Figure 6 is a perspective ,view of one'of character comprising spacedshoe members connectedby chal-iS and arranged around'aj pneumatictire,each"of said shoes having secured thereto calks of-a particularandpe-zV culiar formation which, engaging-withice.

or slippery surfaces, will embed themselves therein and positivelyprevent the wheelfrom skiddi'n'g. .f

A further object is the productionvofan' anti-skidding device forpneumatic gtired` wheels comprising a pluralityof.equi-dis tantly spacedshoes each having on'its outer surface ahollow lcalk 'whose' side wallsvare arched and'ofa greater 'length than-the e'nd walls thereof,wherebyithe said-side:Walls will graduallylmt rmly embed :themselves inicyor other slipperyfsurfaces.before the end walls of`the calkscome incontact with vcumferentially around a'pneumatie tire, each 'of saidshoes being provided withoutstandsuch surfaces, and consequently preventstill further skidding in any direction. A still further. object is theproductiono an anti-skid device for vehicle wheels in-4 cluding aplurality of equi-distantly spaced shoes connected by chains andarranged ciring metallic calks, each offsaid calks being in the natureVf a hollow body whosel side walls are of greater length lthan the' endwalls thereof, they securing means for' the shoesi serving as contactmembers for engagement with jthe tire casing to more eil'ectively retainthe shoes in proper position thereon, while in addition to this, thesaid shoes are' formed with suction openings which assist the .securingmeans for the calksin properly retaining the shoes positioned on thetire.

The foregoing, and other objects which will appearl as thenatu're of theinvention is better understood, may be accomplished by a construction,combination and operative arrangement of parts, suchas is disclosed bythe drawings which accompany and which form part of this application.

.Figure 2 is an edge view thereof. f

.Figure is a sectional-view on an' enlarged scale, and4 approximatelyonthe linee-f3 of 1arged' scale, and .approximately on the line Figure 5is a view loo-king the ealks'detached yfnom the shoe. f

Referring now to the drawings' in detail,

tire 2.

-Arranged around-the sides', at the beaded -edgeof the tire,'are side-chains .3. Suitable means 4; are provided for connecting the endlinksgof the side chains.v On certain of the 'links` of the side chains,in equi-.distantly spaced relation to .each other, are the round-l edends of plates 5.' These'pl-ates, are preferably. constructed of.bendablel metal, but are of sufficient strength' to perform the pur-`F`gure l*l isa side elevation of'ua pneumatic l* tiredwheel-providedwith thel in iprovement.4

toward thel in# 4' poses for which they4 are devised. The plates 5`havetheir free .ends bent and extended faces of the shoes and againstthe bodies of the. said plates.` Thus one end ofeach of the plates isprovided'with a hook and `the other y On the outer or tread face ofeachof the shoes, at the center thereof, there is secured .the 'archedbody portion 9 of a calk. The

calkfis-n the nature of a hollow member,

{throughslots 6 adjacent to the edges of J 1 fabric shoeswhicharearranged around the tire. VThe plates vare then bent over theouter having o utwardlyinclined end vwalls 10 l whose edges arestraight, and arched outwardly vinc'linedside walls .11, whose edges ythe calks, at the lcenter thereof, are of a are struck at a curvature.-The side walls of greater length than that of the end walls.

By arrangingboth the side and end walls i at outward inclinations withrespect to the body, a more effective .gripping surface can be obtainedby the calks on the icy surface.

By providing the (side walls with the round` ed or curved engaging edgeswhich are of a greater length than the end walls,the edges o f the saidside walls will embed themselves in the icy surface .before the saidsurface is engaged by the edges of the angle end fvvalls,l

and as a consequence, the wheel Will be effectively sustained againstskidding either longitudinally or laterally. The securing means for thecalks are in the. nature of bolts, the heads l2 thereof resting .ontheinner faces of the shoes, and being arranged -in contact with theouter surface of the tire serve, .in addition .with the suctionopenings, to positively prevent either the lateral or circumferentialmovement lof the shoes on the tire.

It is believed that the foregoing description, whenv taken in connectionWith the drawings will fully set forth 'the construction and advantagesof the improvement.

Having described the invention, I claim In combination with a pneumatictired Wheel, of anti-skidding means therefor, comprising` side chainsarranged against the tire, equi-distantly spaced plates having eyeportions engaging certain of )the links of the chains, hooks on theouter nds of the plates, fabric shoes arranged ovey the tire and engagedby the hooks of the/plates,'and a hollov calk on each of the shoescomprising a member whose side walls are arched and of In testimonywhereof I aix my signature.
